SHEET-METAL CONTAINER.

Application filed .Tune 27, 1921. Serial No. 480,613;

T0 all whom it may cof/wem.'

Be it known that I, CrmnLns'NnLsoN, la citizen of the UnitedStates, and resident of the city of St. Louis and Stat-ey of Missouri, have invented certain new and useful Improvements in Sheet-Metal Containers, of whichr the'following is a specification containing a full, clear, and exact description, reference being had to the yaccompanying drawings, forming a part hereof.

My invention relates to improvements in sheet metal containers and has for itsv primary object a metal container for containing bricks of ice cream, Thevbottom and the sides being formed `rof separate pieces and are secured together by interlocking their edges. The interlocking edges are turned underneath the bottom so that the sides present a smooth surface.

A further object is to construct a metal container which has the joining edges of the sides and bottom turned underneath, so that they rest on the bottom of the container and thereby eliminate any possibility of the seams opening or being spread open while ice is being packed aroundthe container.

In the drawings,

Fig. 1 is a perspective view ofthe bottom portion of the container, showing my improved seam or joint.

Fig. 2 a vertical sectional view with the bottom secured along the side edgesonly, the end seams not being formed.

Fig. 3 a fragmental section taken diagonally across one of the corners.

Fig. 4 a fragmental perspective view of the bottom at it appears when ready to be secured to the container. f

Figs. 5, 6, 7 and 8 are diagrammatic views showing the various steps necessary to form the seam.

In the construction of my device I employ a container having side walls 9, end walls 10 and a bottom 11. The bottom 11 is provided along its side edges withv hooks 12. These hooks 12 are adapted to be secured within the hooks 13 formed along the side walls 9. The bottom 11 is also provided withsimilar hooks along its two end edges which are secured within similar hooks formed in the endV walls 10. The `hooks on the end walls 10 arek similar in construction to the hooks 15 formed von the side walls 9.

Referring to Figs. 5, 6, 7 and 8,"1 will describe the method of forming myj/improjection 1&1 and Fig. 8,' the finishingof the seam in'which the portion 9 is bent'upwardly so that it extends at right angles to the portion 11. When this has been completed the corner 16 is filled out with solder. (See Figs. 2 and 3.) This makes the container water tight and leaves a perfectly smooth edge around the bottom so that ice and salt can be tightly packed around the lower edges of the sides and rammed down with a stick without any danger of forcing the seam which binds the bottom and sides together apart and causing leakage.

.In assembling the device, it is preferable to form the hooks 14 along the sides 9 and the hooks 12 along the bottom, leaving the edge 17 projecting from one of the ends 10 and while the edge 18 on both ends of the bottom 11 is bent downward at right angles to the bottom 11, the opposite side 10 is provided with a vertical seam 19. This seam is left-open, and the end 10 which contains the seam is bent so as to extend in the same plane as the sides 9. The bottom 11 is then slipped into place by interlocking the hooks 12 and 13 and pushed forward until the downturned portion 18 contacts with the portion 17. It will'be noted in Fig. 2 that the portion 17 extends beyond the portion 18.

After these two portions have contacted, the

and 18 are folded over against the bottom 1l, thus securing the bottom and sides of the container together. The solder is then run around all four edges of the inside of the container and may also if found desirable, kbe run around the fiange lying on the bottom of the container', so as to make two solder joints instead of only one and render the container doubly leak proof.

Having fully describe-d my invention, what I claim is:

1. A sheet metal container having its side walls formed of a single sheet of material and held together along one side, two of the opposing walls of the container being provided along their' lower margins with integral and inwardly extending hooked portions, and the remaining side walls having portions extending below said hooked portions, a bottom for said container having rectangular out away portions its corners and two of its opposing edges provided with inturned hooked portions adapted to be slipped into engagement with the hooked portions of the walls of the container and having its remaining two edges bent at right angles to the bottom, which portions are adapted to contact with the downwardly projecting portions of the sides of the container, and said contacting portions being adapted tobe folded inwardly and upon each other, so as to form an interlocking connection. i

2. A sheet metal container having sidel walls formed of a single sheet of material and provided with' a vertical seam along one side, the two opposing walls adjacent the seam being provided along the lower margins with integrally formed inwardly extending hooked portions,- the remaining two vside walls having portions extending below the hooked portions, a bottom forfsaid container having a rectangular cut away portion at each corner, two of its opposing edges provided with hooked portions adapted to be slipped into engagement with the hooked portions of the walls, the remaining two edges being bent downward at Vright angles to the bottom and adapted to contact with the downwardly projecting portions of the sides of the container, said contacting portions adapted to be folded inwardly and upon each other so as to form anv interlocking Connection, all of said connections when formed lying close along the bottom of the container, the two last mentioned opposing connections adapted to lie between the opposing edges of the two first mentionedconnections.

In testimony whereof, I have signed my name to this specification.
